How Much Does PostHog Cost in 2026?

PostHog is what you'd build if you started product analytics from scratch today. Rather than buying Mixpanel ($free up to 1M events) + LaunchDarkly ($10/mo flags) + Hotjar ($39/mo replays) + Typeform ($25/mo surveys) + Sentry ($26/mo errors) = $100+/mo for 5 tools, PostHog bundles everything into one platform with free tiers that typically cover all 5 products for early-stage companies. Free tier breakdown: 1M events (matches Mixpanel free), 5k session replays (~100/day), 1M feature flag requests (enough for a 100k-user SaaS), 100k exceptions (adequate error monitoring), 1.5k survey responses/mo, 1M data warehouse rows, 10k data pipeline events, 100k LLM analytics events, $20 in AI credits, 50GB logs ingested — all free, monthly. For a seed-stage SaaS, this is often $200-500/mo worth of tooling at zero cost. Pay-as-You-Go starts at $0 with usage-based pricing after free tier: $0.00005/event (scales to $0.0000090 at 250M+), $0.0050/replay (scales to $0.0015 at 500k+), $0.0001/flag request. At 10M events/mo: (10M - 1M) × $0.00005 = $450/mo — comparable to Mixpanel Growth at same volume. Unlimited team members on all plans is genuinely unique. SSO on Free via Google/Github/Gitlab. Where PostHog wins: bundled tool replacement, generous free tiers, developer-first UX. Where it loses: some individual products (session replay UX, for instance) are less polished than category specialists (Hotjar).
